Soybean isoflavones play diverse roles in human health, including cancers, osteoporosis, heart disease, menopausal symptoms and pabulums. The objective of this study was to identify the quantitative trait loci (QTL) associated with the isoflavones daidzein (DC), genistein (GeC), glycitein (GlC) and total isoflavone contents (TIC) in soybean seeds. A population of 184 F2:10 recombinant inbred lines derived from a 'Xiaoheidou' x 'GR8836' cross was planted in pot and field conditions to evaluate soybean isoflavones. Twenty-one QTL were detected by composite interval mapping. Several QTL were associated with the traits for DC, GeC, GlC and TIC only. QDGeGlTIC4_1 and QDGlTIC12_1 are reported first in this study and were associated with the DC, GeC, GlC and TIC traits simultaneously. The QTL identified have potential value for marker-assisted selection to develop soybean varieties with desirable isoflavone content.
大豆异黄酮在人类健康中发挥着多种作用，包括癌症、骨质疏松症、心脏病、更年期症状和婴幼儿食品等方面。本研究的目的是鉴定与大豆种子中大豆异黄酮大豆苷元（DC）、染料木黄酮（GeC）、黄豆黄素（GlC）和总异黄酮含量（TIC）相关的数量性状位点（QTL）。将一个由“小黑豆”דGR8836”杂交产生的包含184个F2:10重组自交系的群体种植于盆栽和田间条件下，以评估大豆异黄酮。通过复合区间作图检测到21个QTL。有几个QTL仅与DC、GeC、GlC和TIC的性状相关。QDGeGlTIC4_1和QDGlTIC12_1在本研究中首次报道，且同时与DC、GeC、GlC和TIC性状相关。所鉴定的QTL在标记辅助选择以培育具有理想异黄酮含量的大豆品种方面具有潜在价值。
